I have about 500 miles on it now, in its bone stock configuration. Will continue to ride it as such until my hunting season/cold weather training regimen starts next month. My biggest/only complaint about the stock config is the Orbea saddle... I pretty much hate it. Maybe I'm spoiled by the Spesh saddles on my other bikes, idk. I'm pleasantly pleased w/ the facory Vittoria tires on the Orca... much better/grippy than the factory Spesh tires that came on my Roubaix. GP4000s made a huge improvement on the Roubaix, so I'm expecting a comparable improvement on the Orca. I'm faster on the Orca than on my Roubaix, but that's likely due to the more aggressive/aero position on the Orca, as the two bikes weigh pretty much the same.
I've picked up a set of new Fulcrum Racing 5's which I'll use to swap out the factory Orbea 28's, plus the GP4000s. And I'll likely be asking Mrs. IANative for a new Spesh saddle (Romin, Toupe?) for Christmas. But all in all, I couldn't be more pleased with my decision to buy the Orca BRV. Fast and comfy.
